DEVICE FOR ATTACHING HANDLES TO PLOWS.

SPECIFICATION forming part of Letters Patent No. 362,321, dated May 3,1887.

Application filed February 28, 1887. i

To all whom it may concern.-

Be it known that 1, CHARLES F. SEAMAN, a citizen of the United States,and a resident of Hamburg, Berks county, Pennsylvania, have inventedcertain Improvements in Devices for Attaching Handles to Plows, of whichthe following is a specification.

One object of my invention is to provide for' the ready application ofthe handles to the plow and their support in proper position on" theplow prior to making the permanent con nections, a further object beingto provide for the locking of the attaching device by the straining-boltusually employed in connection with the two handles.

In the accompanying drawings, Figure 1 is a sectional plan view of partof a plow and its handles with my improved handle-attaching device. Fig.2 is a side view of the plow with part of the landside broken away andone of the handles shown by dotted lines. .Figs. 3, 4,

side an eye, d, and at therearend of said shank and 5 are perspectiveviews of the handle-attaching plates forming part of my invention, andFig. 6 a transversesection illustrating the locking. action of thestraining-bolt.

In Fig. 1, A represents part of the moldboard,and B part of thelandside, of an ordinary plow, D D being the handles of the same. Befo eattaching the handle structure to the plow it is provided with the usualtransverse braces, so that the two bars D D will occupy the properrelation to each other.

It is advisable to provide some simple device whereby the handlestructure may in the first instance be attached to the plow, and bywhich it will be retained in its proper position in relation to the plowwhile it is being permanently fastened thereto. The devices which Iemploy for this purpose consist of latchplates F and G, the plate Fbeing attached to the inner side of the mold-board of the plow and theplate G being secured to the handlebar D. The plate F has a projectingwing, a,

suitably bent to conform to the curve of the inner side of themold-board,to which the wing is rigidly bolted or riveted, so that theshank b of the plate projects from the inner side of the mold-board atan angle similar to that of the bar D of the handle structure whenthelatter is in place. The shank I) has on the inner side of the plow bymeans of the anglebrace I,

Serial No. 229,140. (No'modelJ is a hook, f, and on the plate G of thehandlebar is a projecting tongue, 9, for adaptation to the eye (I, and alaterally-projecting wing or finger, h, for engagement with the hook fon the plate F.

' The tongue 9 can be readily slipped into the eye (1 of the plate F,and thelug h then dropped into the hook f, and when this has been donethe handle structure will be supported in its proper position in respectto the plow,and the bar D of the plow can be permanently secured to theouter portion of the mo1d-board by means of the curved brace H, and thelower end of the handle-bar D can be secured to the landone wing ofwhich is bolted to said landside and the other wing to the lower end ofthe handle-bar.

It is usual to provide the handle structure of a plow,near thelower end,witha transverse straining-bar, m, for 'forcing apart the lower ends ofthe bars D D and maintaining the landside and mold-board of the plow intheir proper positions. I utilize this straining-bar to lock thelatch-plates G and H in position, each of said plates having a beveledopening, it, which openings, when the two parts are in engagement witheach other, coincide and form a beveled recess for the reception of thebeveled end of the straining-bar m, the opposite end of which isthreaded for the reception of a nut, p, having its bearing upon thehandlebar D.

The plates F and H are bolted to the moldboard,and the brace I is boltedto the landside before the faces of said mold-board and landside areground and polished, so that as the heads of the securing-bolts areground off flush with the faces of the mold-board and landside, and notafterward disturbed, they afford no obstruction to the free passage ofthe plow through the soil.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s
